To all whom it may concern Be it known that we, SAMUEL K. DENNIS andARTHUR HOLSEY, citizens of the United States, residing at Chicago, inthe county of Cook and State of Illinois, have invented certain new anduseful Improvements in Fertilizer Attachments for Corn-Planters, ofwhich the following is a specification.

Our invention relates to fertilizer distributers, and in particular tosuch of the class that are operative in connect-ion with corn plantersfor the purpose of distributing ma terial at each hill, and having themovement of the parts thereof controlled by the planter mechanism; theobject of our invention being to provide a mechanism that may be readilyattached to or detached from the frame of the planter, quickly adjustedin a manner to regulate the quantity of material distributed andaccurate and efficient in operation. W's attain these objects by meansof the mechanism illustrated by the accompanying drawings, in which--Figure 1 represents a top plan view of a corn planter having ourinvention embodied in the construction thereof; Fig. 2 is a sideelevation of Fig. 1, partly in section; Fig. 3 is a front elevation ofpart of the planter frame and designed to illustrate the manner ofmounting the receptacle "for the fertilizerthereon and connecting itwith the seed delivery mechanism; Fig. 1 is a sectional side elevationof part of Fig. 8, on an enlarged scale, and designed to illustrate theopera-- tion of'the valve mechanism for the fertilizer and theconnection thereof with the seed controlling valves; Fig. 5 is a topplan view of a combined seed dropping and fertilizer distributing valve;Fig. 6 is a side elevation of Fig. 5; Fig. 7 is a plan view of the lowerend of the fertilizer conduit;

side elevation of Fig. 12.

The same reference characters designate like partsqthroughout theseveral views.

The combined, corn planter and fertilizer distributer includes a wheeledframe 1, subters.

stantially U-shaped and having the front end thereof pivotally connectedwith a transverse member 2 of the draft and runner frame by means ofdraft brackets 3 and coupling pins 41, and 5 represents the drafttongue.

8 represents the driving axle journaled in bearings 7 carried by thewheeled frame and having traction wheels 8 secured to opposite endsthereof, and 9 represents a transverse-membfi-of the wheeled frame, uponwhich are mounted a hand lever 10 operative in a manner. to control therelative positions of the runner and. wheeledframes, and a foot lever 11operatively connected with the seed dropping mechanism.

12 represents bracket members secured to the side members of the Wheeledframe, arranged vertically and having securedto the upper ends thereof atransverse bar 13.

1 1 represents bracket members secured to opposite ends of member 2 ofthe runner frame and having integral therewith rearwardly inclined seedconduits 15, to the lower ends of which are secured the rear ends offurrow opening runners 16, the

front ends of the runners being connected with the bracket members bymeans of bars 17.

18 represents base members secured to the upper ends of brackets 14 andhaving a feed. shaft 19 journalcd therein that may be connected with theseed delivery mechanism carried by the seed hoppers 20 in any preferredmanner.

21 represents base members secured to oppositeends of bar 13 and havingjournalcd therein a feed shaft 22, upon which are mounted feed worms 23,including sleeve members 24; having helically arranged ribs 25 thereonthat are inclined in opposite directions axially from near the center ofthe sleeves and having gradually reduced diame- The bottom of the basemembers conformin general shape to that-of the feeding worms and areprovided with central angular feed openings 26, the areas of which arecontrolled by means of sliding plate valves 27 mounted in the basemembers and operatively connected with adjusting screws 28. The feedopenings are surrounded by depending flanges 29, to which are connectedtwo-part coupling members 30, having the upper ends of flexible conduits31 secured thereto, the coupling members being provided with laterallyprojecting wing members 32 that'are received between ear members 33integral with the base members and retained therein by means of pins3st.

35 represents short, cylindrical feed conduits that are secured to thelower ends of the rear walls of the seed conduits 15 by means of pins36, having the lower ends of the flexible conduits, secured thereto andprovided wfitih laterally projecting trunnionmembers 37, upon which arejournaled rocking valves 38 having'central web members 39 concentricwith the axes of the trunnions and adapted to open and close the lowerends of the conduits 35.

40 represents the clutch tripping shaft of the planter mechanismcontrolled in a common way by a checkwire 4:1, or by the foot lever 11.

42 represents a first drop seed valve mounted at the upper end of theseed conduit and operatively connected with the clutch trippin shaft,and 43 a rod having the lower en thereof connected with the rockingvalve 38, and the upper end thereof to an arm 44 secured to the clutchtripping shaft, whereby the two sets of valves are actuatedsimultaneously.

45 represents a second drop seed valve pivotally mounted at the lowerend of the seed conduit and actuated by means of a plunger bar 46,having the upper end thereof operatively connected with the clutchtripping shaft.

47 represents a rearwardly-extending conical wing member integral withvalve 45 at its upper end and operative as a deflector or spreader forthe fertilizer as it is delivered from the lower end of the feedconduits 35, the spreader moving toward the conduit as the second dropvalve is opened.

The fertilizer feed shaft 22 is operatively connected with the axle 6 ofthe planter by means of a sprocket chain 48 and sprocket members 49 and50, upon the axle and feed shaft, respectively. and a clutch mechanism51 carried by the feed shaft and controlled by a clutch tripping lever52. The base members 21 of the fertilizer receptacle have outwardly andupwardly diverging walls 53 provided with annular flanges 54 at theupper ends thereof that receive the lower ends of cylindrical sheetmetal fertilizer receivers 55 that are secured thereto by means of bolts56.

57 represents a bridge member having opposite ends thereof secured tothe diver ing walls of the base members and provided w th a verticallyarranged stem 58. the av s of the stem being in vertical alinementwiththe feed opening 26. and rotatahlv mounted upon the stem is an agitator59. having a curved fin er portion 60 that turns in close proximity tothe diverging walls of the base. the agitator being given intermittentrotaea-nave tion by means of a pin 61 carried by the feeder mechanismand engaging with radially extending wings 62 integral with theagitator. The agitator is slidably mounted upon the stem 58 and isyieldingly pressed downward. by meansof a spring 63 coiled about thereduced upper end of the stem and inclosed within a thimble 64 that isconnected with an axially alined boss portion 65 in tegral with theagitator, the construction permitting the agitator to ise if the pin 61does not engage properly therewith.

ln operation the fertilizer is being constantly agitated above thefeeding worms, and the latter move it toward the feed open ings and itfalls to the bottom of the feed conduits, that are closed by the valves38, and when the seed dropping valves are actuated by the plantermechanism the valves 38 are rocked about their axes, permitting, thematerial to pass over the conical spreaders carried by the second dropseed valve, whereby the material is directed out- Ward from theperiphery of the conical Spreaders, but will not come in contact withthe seed as it drops into the furrows.
